New Meditation Technique

So, today I attempted to try something new for my meditation technique. Lately I have been humming the mantra sounds for each chakra out loud- Lam, Vam, Ram, Yam, Ham, Om and then silence for the 7th chakra or I repeat the mantra Om again. Today I tried just silently repeating each mantra while deep breathing in and out. I eventually reached the alpha state. It felt as though I was floating in the middle over nowhere intermittently. As soon as I would get excited and realized I had reached this state, I would lose the feeling of nothingness. A calm feeling also came over me and I was able to suddenly recognize that I was holding tension in various areas of my body. As I breathed in with each chakra, I visualized the universal life force entering my root chakra. As I exhaled, I visualized my energy around me expanding and the darkness emptying from each chakra. Once I completed working on each chakra, I just focused on my breath and energy entering my root and crown chakra on and off. At one point, I had a very clear image of a bubble of golden liquid that was rising upwards in my mind. I was actively meditating for almost an hour altogether. This was right after I woke up around 5:53am.
